Just in time for the holidays I'm proud to present to you My Maps Editor by Google, now available for download in Android Market! In just four months of my 20% time and with a little help from the 20% time of my coworkers this application has gone from an idea in my head to a full application ready for you, really demonstrating the ease and power of developing on Android.

With this application you can create, edit, share, and view personalized maps on your Android powered phone synchronized with the My Maps tab on Google Maps. Create a map on your desktop computer using Google Maps and then take it with you on the go and update it on location. My Maps Editor by Google supports full editing functionality for markers, lines, and shapes on maps, plus the ability to mark your location using GPS or attach a photo directly from your phone. Your maps are automatically synchronized with your My Maps on the web. Check out this tour of Google Mountain View that I just created on my phone:

There are plenty of ways to put this to good use during the holiday season:

Plan out your holiday shopping. Create a map on your computer with markers for all of the stores you need to visit. Color code the markers according to importance, category, or sales. Then as you visit each store, change the icon to indicate that you've been there and list what items you were able to get in the description. If you find a store you didn't think of, you can quickly add a marker for it to help future planning.

Make a map of holiday decorations and displays that you see. Every time you see an interesting holiday display, use the Mark My Location feature to create a marker, then edit the details and add a photo of the display right from the phone's camera. Share your map with your friends and family to show them the best holiday displays in your area. Just go to the maps list, tap and hold on your map, and select Share Map to share it right from your phone.

Keep track of your travels. You can map out your travel plans and take them with you wherever you go. Add markers while you travel to mark interesting places, and take lots of pictures and attach them to the markers. Then when you get back, you can share the map with your friends and show everyone what your did on your vacation with a map and pictures to help them really visualize the trip.

The fun doesn't stop once the holidays are over. The possibilities are endless when your maps are in the palm of your hand (try making a map of running routes to keep yourself to your New Years resolution!). Don't take my word for it, go download My Maps Editor by Google from Android Market (currently available on the T-Mobile G1) and see for yourself!
